The 67-147 9.0mm Dia. x 54.0mm FL is a Plano-Convex lens, uncoated, sourced from the renowned optical components vendor, Edmund Optics. This lens, with a diameter of 9.0mm, is designed to provide a focal length of 54.0mm, making it suitable for a wide range of optical applications.
The lens's geometry is characterized by its edge thickness of 1.63mm and center thickness of 2.0mm. The effective focal length (EFL) is 54.0mm, and the radius of curvature (R1) is 27.91mm. The back focal length (BFL) is 52.69mm, and both the inner and outer radii are 0mm, indicating a plano surface on one side of the lens.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The wavelength for this lens is 587.6nm. The lens is uncoated, which means it does not have any anti-reflective coatings. This may result in higher reflective losses and lower transmission compared to coated lenses, but it can be advantageous in certain applications where specific reflective properties are required.
